Hi..has anyone used arduino.h header file on due, to change PWM freq.?

Hello

Im working with an arduino due, and id like to change the PWM frequency. I found this link:

http://www.kerrywong.com/2014/09/21/on-arduino-due-pwm-frequency/

the article is useful, but i could not get the arduino.h header file mentioned in the article....has anyone used this? If so could you please share the link where this library is available..?

the article is useful, but i could not get the arduino.h header file mentioned in the article.

What do you mean by "I could not get the Arduino.h header file..."? The Arduino.h header file is included in every distribution of the IDE, and is included by the IDE in every sketch. You do not need to explicitly include it.

Are you on Windows or some other operating system? The location of the file is different. In Windows it's in your user profile (Roaming, I think) in an Arduino folder, under SAM, not AVR.

thank you...im using windows....sorry...but im just learning so some of the terms seem had to get at first....thanks i got it correctly with ide 1.5.7...another thing which i did wrong was look under AVR...thanks for the help
